Abstract

A software framework for the solution of electrochemical processes will be presented.

In a first part the set of equations that are considered is given. It is explained that frequently used models are in fact subsets of these equations covering ion transport, electro-osmotic flow on micro and nanometer scale, electrophoresis, MHD effects, ion transport influenced by a magnetic field &c..

It is further explained how the framework is structured in order to achieve this flexibility. The basis consists on grouping blocks of one or several equations that can be solved in an almost arbitrary sequence. For instance strongly coupled fields like flow and pressure (mass, momentum and energy conservation) or ion transport (mass conservation and electroneutrality) are solved simultaneously whereas the temperature field is often treated separately, or weakly coupled, it's effect spanning the other physics systems. These blocks can then be configuration such that they best suit the physics of a specific testcase.

Then aspects of numerical discretisation and also grid generation are highlighted. Finally typical examples will be treated. Ion transport under laminar and turbulent flow transport, electro-osmotic flow, magnetic influence on ion transport and also the highly temperature dependent anodizing process.
